After the conditions are edited, if the [ESC] key is pressed, the dialogue box will close without saving the edited condition. If the [F7: Complete] key is pressed, the edited content will be saved and the dialogue box will close.

 

The following information is about the items that are to be applied commonly for welders. Refer to [Chapter 4. Arc welder setting] for the items that can be set specifically for individual welders.

 

The contents of the common items may vary in their model type, units and range. Refer to each table of individual items when it comes to the difference of welders.

 

(1)   Condition number

	Name	Range
Common to all welders	Condition number	1 ~ 32

Designate the welding start condition number for editing. (32 conditions can be designated and used)

 

(2)   Description

	Name
Common to all welders	Description

Record the description about the relevant welding start condition.

 

(3)   Synergic code

	Name	Unit	Range	Default
HRWI	Synergic code	-	-	040
GB2/GZ4/GE2	Synergic code	-	-	0340/1153/0340
ESAB, Fronius MEGMEET	Not supported
EWM	JOB Nr.(synergic)	-	-	185

Set the synergic code that needs to be sent to the welder. The code value can be set through the synergic code selection dialogue box. It is possible to enter the synergic code selection dialogue box by pressing the [Help] key, or pressing the [Enter] key when the cursor is placed on the welding environment code.

 

(4)   Gas preflow (When controlling the gas signal)

	Name	Unit	Range	Default
Common to all welders	Gas preflow	Second	0.0 ~ 10.0	0.5

Set the time for emitting the shield gas in order to separate the welding area from the atmosphere before starting welding.

(5)   Welding current/ Welding power / Feeding speed

	Name	Unit	Range	Default
HRWI	Welding current	A	0.0 ~ 500.0	100
GB2/GZ4/GE2	Welding current	A	30.0 ~ 350.0	150
Fronius	Welding power	%	0.0 ~ 100.0	10
ESAB/EWM	Wire feeding speed	m/min	0.0 ~ 25.0	3.1
MEGMEET	Welding current	A	30 ~ 400	150

Set the value that corresponds to the welding current. This is for the current that will be used for the main conditional welding, while the current to be used for the initial condition as well as the end condition will be decided based on the ratio of this value.

 

(6)   Welding voltage correction/ Arc length correction

	Name	Unit	Range	Default
HRWI	Welding voltage correction	%	50.0 ~ 150.0	100
GB2/GZ4/GE2 ESAB/EWM	Welding voltage correction	V	-10.0 ~ 10.0	0
Fronius	Arc length correction	%	-30.0 ~ 30.0	0
MEGMEET	Welding voltage correction	%	-30.0 ~ 30.0	0

When it comes to digital welding, the welding voltage selected due to the welding current from the synergic data will be used in many cases, the welding voltage will not be entered directly. If needed to change the welding voltage selected automatically due to the synergic data, it is required to set the offset value for the target voltage based on the relevant welding voltage.

 

(7)   WCR wait time

	Name	Unit	Range	Default
Common to all welders	WCR wait time	Second	0.0 ~ 10.0	2

Displays the WCR input wait time. If the WCR signal is not fed within the time, retry will be performed. However, if the count of retry is 0, an error will be generated and the robot will stop. The functions related to retry, such as restart methods and retry count, can be set from the welding auxiliary condition (Refer to 5.5. Welding auxiliary condition – retry and 5.6. Welding auxiliary condition - restart).

 

(8)   Robot delay time

	Name	Unit	Range	Default
Common to all welders	Robot delay time	Second	0.0 ~ 10.0	0

Set the wait time before the robot performs welding by following the welding path after the arc welding gets started normally. It has nothing to do with the initial condition and the robot can move while the initial condition is being processed.

 

(9)    Initial condition time

	Name	Unit	Range
Common to all welders	Initial condition time	Second	0.0 ~ 10.0

Set the time for maintaining the initial current value when welding gets started.

 

(10) Initial welding current / Welding power / Feeding speed

	Name	Unit	Range	Default
HRWI GB2/GZ4/GE2 MEGMEET	Initial welding current	%	20 ~ 200	120
Fronius	Initial welding power	%	20 ~ 200	120
ESAB/EWM	Initial feeding speed	%	20 ~ 200	120

Set the output welding current during the initial condition hold time when starting arc welding. Set it based on the % against the welding current of the main condition.

 

(11) Initial welding voltage correction / Arc length correction

	Name	Unit	Range	Default
HRWI	Initial welding voltage correction	%	50.0 ~ 150.0	100
GB2/GZ4/GE2 ESAB/EWM	Initial welding voltage correction	V	-10.0 ~ 10.0	0
MEGMEET	Initial welding voltage correction	%	-30.0 ~ 30.0	0
Fronius	Initial arc length correction	%	-30.0 ~ 30.0	0

Set the output welding voltage during the initial condition hold time when starting arc welding. Set it based on the corrected value against the synergic voltage.

 

(12) Slope time

	Name	Unit	Range
Common to all welders	Slope time	Second	0.0 ~ 10.0

Set the time for processing the change of current between the initial condition and the main condition as a slope.

 

(13) Permitted excess time

	Name	Unit	Range	Default
Common to all welders	Permitted excess time	Second	0.0 ~ 10.0	0

 

Set the allowable limit exceeded time for the welding current/voltage and the feed motor current. If the welding current/voltage or the feed motor exceeds the limit for longer than this time limit, restart will be performed. However, if the count of retry is 0, an error will be generated and the robot will stop. The functions related to retry, such as restart methods and retry count, can be set from the welding auxiliary condition (Refer to 5.6 Welding auxiliary condition – restart). If the time is set as 0, the arc limit monitoring function will not be used.

 

(14) Voltage upper limit/voltage lower limit

	Name	Unit	Range
Common to all welders	Voltage upper limit /Voltage lower limit	V	0.0 ~ 100.0

Set the upper and lower voltage limits to be applied while carrying out welding. An error will be generated when the limit is exceeded for longer than allowable time.

 

(15) Current upper limit/current lower limit

	Name	Unit	Range
Common to all welders	Current upper limit/ Current lower limit	A	0 ~ 1000

Set the upper and lower current limits to be applied while carrying out welding. An error will be generated when the limit is exceeded for longer than allowable time.

 

(16) Motor current upper limit/Motor current lower limit

	Name	Unit	Range	Default
GB2/GZ4	Motor current upper limit/ Motor current lower limit	A	0.0 ~ 50.0	10/0
Other welders	Not supported

Set the motor upper and lower current limits to be applied while carrying out welding. An error will be generated when the limit is exceeded for longer than allowable time.
